I was just confirming a friendship on Facebook (yes, yawn) and the UI seemed different somehow, but I couldn't quite place it. Then I realized there were a few less checkboxes for how you know the person. I read them all but couldn't remember what was there before except "We hooked up".
What else disappeared? Is this part of Facebook trying to grow up and be more mass-market applicable?
Sorry, this is probably old news. I don't tend to respond to all my requests (image cropped due to browser height) and so just haven't noticed until now.
